Solution Overview

Problem

In some scenarios, the sidelink transmission rate in new radio (NR) sidelink transmission is relatively low, failing to meet the transmission rate requirements of services.

Innovation Solution

A CA parameter configuration method where a first device sends information to a second device to indicate a target CA parameter for sidelink services, enabling carrier aggregation (CA) data transmission to improve transmission rates and reception effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If carrier aggregation is implemented to support 5G services, then network capacity and data transmission rate are improved, but system complexity and difficulty of network management increase

Engineering Contradiction:
Improvenetwork capacityVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the carrier aggregation configuration process into distinct phases: determining whether to support carrier aggregation, selecting specific aggregation modes based on service types, and configuring parameters differently for each mode. This segmentation allows the complex carrier aggregation system to be managed through structured, modular configuration steps, reducing overall system complexity while maintaining high network capacity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic configuration of carrier aggregation parameters based on real-time network conditions and service requirements. The system can dynamically switch between different aggregation modes (e.g., contiguous vs. non-contiguous frequency aggregation) and adjust resource allocation accordingly, allowing the network to adapt to varying traffic demands while maintaining manageable complexity through automated decision-making algorithms

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If multiple aggregation modes are supported for different services, then service adaptability is improved, but configuration complexity increases

Engineering Contradiction:
Improveservice adaptabilityVSAvoidconfiguration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies different configuration parameters and aggregation modes tailored to specific service types and frequency bands. For example, contiguous frequency aggregation is configured for bandwidth-intensive services like video streaming, while non-contiguous aggregation is used for latency-sensitive services. This localized optimization allows high service adaptability without requiring the entire system to handle all possible configurations simultaneously, thereby managing complexity

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system performs preliminary determination of carrier aggregation support and pre-configures appropriate parameters based on service requirements before actual data transmission begins. By pre-establishing configuration rules and selecting aggregation modes in advance based on service type identification, the system avoids complex real-time decision-making during data transmission, reducing configuration complexity while maintaining versatile service support

Inventive Principle:
Principle #10Preliminary action
